Benefits of technology

The design enhances working efficiency by allowing easy opening and re-closure of the bag, preventing content oxidation, and improves filling efficiency with a self-standing capability adaptable to various contents.

Problems solved by technology

However, in the case of this flat-bag-type fastener bag, a portion from which a content filling hopper is inserted into a bag body is not widened so much, and this matter constitutes an obstacle for improvement of working efficiency.
In addition, there may cause a case such that a cutting-starting portion of the cut-open portion, from which the bag is torn and opened, is not well formed.

Abstract

There is provided a fastener bag capable of improving working efficiency for the filling of inner content and forming a bag cut-starting portion. The bag is formed as gusset-type packaging bag, to which a fastener for freely opening or closing the packaging bag is attached. The fastener has a male portion to which a projected thread is formed and a female portion to which a groove is formed so as to be engaged with the projected thread. Base portions of the male and female portions are attached to an inner surface of one of the flat surface portions or side surface portions so that the projected thread and the groove face each other. A cut-tape for separating the flat surface portion into the male portion side and the female portion side is provided between the base portions.

Description

[0001]The present application is based on International Application PCT / JP2003 / 003152, filed Mar. 17, 2003, which application is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to a fastener bag of gusset-type structure which can be easily opened and is provided with a fastener to be freely opened or closed.BACKGROUND ART[0003]In these days, there is high requirement of producing a packaging bag provided with an easily opening mechanism and a mechanism for freely opening and closing an opening of the opened packaging bag. Specifically, it is required to provide a fastener bag having both functions in a technical field of an automatic filling and packaging bag capable of simultaneously filling a content in the bag and packing the bag.[0004]The applicant of the subject application has provided, in order to satisfy the above requirement, an invention relating to a flat-bag-type fastener bag which is formed with a cut-open porti...
